SdfDataSet, DBGrid => FPC3.20 Problems

[DL4MFM]

After a year or so I wanted to update my amateur radio logbook program. Only small files are used and I decided for CSV files to store the data. The records are connetced via DataSource => SdfDataSet => DBGrid. All worked fine, also editing the data records in the DBGrid.

Now, with Lazaraus 2.0.10 and FPC 3.2.0 I have the strange effect, that when a cell in the DBGrid is edited, several other cells of this record are cleared. It is desperate, I couldn't find a solution. Then I connected Lazarus to a FPC 3.0.4 installation and all was perfect again (I would like to use FPC 3.2.0 because of the opensslsockets)

Has anybody the same effect and found a solution or a workaround?

In the attachment you see this effect. Editing the cell with "DL7ABI" into "DL7AAA" clears the next cell. Sometimes are 2 cells cleared
